OILING DEVICE FOR STOCKS AND DIES.

Specification of Letters Patent. Patented Sept. 13, 1910.

Application filed August 5, 1997. Serial No. 387,073.

To all whom 'it may concern:

lle it known that I, Gus'rnv T. E. lInN- iunsnx, a citizen ot the UnitedStates, residing at ('hicago. in the county ot (look and State ot'Illinois. have invented a certain new and useful linprm'eiueut in OilingDevices t'or Stocks and Dies. ot which the tollowing is a Specification.

`his invention relates to devices lor forming' screw threads, and hasfor its object to provide a new and improved device ot' thisdescription.

rl`he itu-'ention is illustrated in the accompanying drawings, wherein.

Iigrure l is a view in part section showing one forni ot device.embodying the invention; Fig. 2 is a sectionI on line 2-2 of Fig.4 t;Fig. 3 is a view showing a modified construction.

Like letters refer to like parts through- .,out the several figures.

l'u forming` screw threads Witha stock and die, tor cxaniple, it isnecessary to apA ply oil at the point where the die eli-gages the partupon which the screw threads are formed. apply this oil under theordinary conditions.

One ot the objects of-niy invention is to proridoa construction wherebythis oil is applied winger-titantly at the proper times and in properamounts.

Referring non' to Fig. l, Iliave. shown al Stof-li' provided with a dieli with a, piece of pipe (l ini-1 position and upon which threads areheine4 made. The handle-piece D for the `stoel: or holder of the die ishollow and Ais pre'leral'ily filled or partially filled irith'oil.lVithin-this handle is a reciprocating' part 'E which is held in pla-cein any desired manner, as by means ot the guidcb l". rlhese guidespreferably lit the i."ecipromting; part E so as to make an oiltightjoint'. A shoulder (l is attached to,

got 't'ornwd ou'.A the. part. lt) and a spring ,Il

is* loi-'ated lit-tween this shoulder and the .gi-hide l". '.lhereciprocatingr part E is prorided with one or more openings 'I ahovethcguide ll, and one or more openings J which are-normally opposite theguide l*` but arranged so that when the guide is moved in the(lit-eethin ot" its-.length one'opcuingr will pass hclow the guide sothat the oil may escapo, the passage hcingffron'i thc handle D throughtho ollieuin'ggs l and al. A stop K is attached to thereciprocating'part E so as to limitte` moreinen uider the tension lt isditiicult and inconvenient to' of the spring H. rl`he escaping oilpasses into the chamber L and thence throughthe conductor M to thepoint, where the threads ot' th die engage' the device acted upon. Itwill thus be seen that the operator by occ. sionally pushing on thereciprocating part E can apply the oil directly to the point of use.

As illustrated in Fig. 3, the guide F is prorided with one or moreopenings F1. The reciprocating part E is provided with a valve device F2which closes seid opening or openings hy mea-ns of the pressure,

of the spring H. A washer or packing F8 may be used it desired to insurea proper joint. When the reciprocating device E is lnoved it opens upthe openings F1 and permits the oil to escape. It. Will be seen that. bythis construction the oil can be easily applied at the proper point, andthat hence less oil is Wasted and the application of a proper amount otoil is insured. It will farther be notedthat When the reciprocating partis moved the Shoulder Gr tends to compress the oil between it and theguide F, thas tending to force the oil. out and secure e proper tiowthereof.

I claim:

l. An oiling device for a stoclt'and die' comprising a hollow handleconnected with the stock, and adapted to contain a liquid,

va reciprocating part Within Said handle and tightly therein so as tonormally prevent the escape of the liquid through the guides, but freeto reciprocate, the guides acting as confining parts hetween'which theliquid is contained, a spring located in the space between Said guidesand Surroundingl a portion of said reciprocating part, one eud ot saidspring engaging one of said guides, and the other end saidreciprocating' -part. and means t'or releasing a port-ion of said liquidby a longitudinal movement ot said reciprocating part.

2. Airoiling device for a stock-and die comprising a. hollow handlecounectod'with the stock, and adapted to contain a liquid,A areciprocating part within 'said handle and extending therealong, twoguides in said hollow handle separated from each other,

said reciprocating part assing through both of said guides and Fittingtightly therein so as to normally prevent the escape of the liquidthrough the guides, but free to reciprocate, the guides acting asconfining parts between which the liquid is contained, and means forreleasing a portion oi said liquid by a longitudinal movement of saidreciprocating part, and a compressing dcvice for forcing the liquid outof said handle when the reciprocating device is moved coinprising anenlargement on said reciprocat 111g part in proximity to the guidethrough which the liquid escapes.

3. An oiling device for a stock and die comprising a hollow 'handleconnected with the stock and adapted to contain oil, two guides at aidistance from each other iocated within'said hollow handle,'areciprocating part passing through both of said guides and fittingtightly therein so as'to prevent the oil fromy escaping between theengaging faces of the guides and said reciprocatingpart,fa1id means forreleasing a portion of said oil when said reciprocating part is moved,said oil escaping through one of said guides, a chamber below the end ofsaid hollow. handle into ,which said l.oil is received, and a pipe atone side of said chamber connecting with said chamber near the backthereof, and having a curved end which discharges the oil at the pointof use.

pAn `oiling device for a' stock and die comprising a hollowhandle'conn'ecte'd with the stock, two guides Within said hollow handleforming between them a liquid chamber, a' reciprocating Vpart lpassingmunicatin g with through both of said guides and proiecting at each endbeyond them, a spring aeaoJ ciated with said reoiprocatin part andlocated between said guides an Within the oil chamber, the openmgthrough which the liquid escapes from said chamber being beyoud saidspring so that the liquid passes the spring before escaping from thechainber said spring adapted to move the recipu rocating part to itsinitial position, and

mea-ns for permitting the escape of the oil when the reciprocating partis moved.

' 5. An oiling device for a stoel: and die comprising a hollen1 handleconnected with the stock and adapted to contain liquid, two guides insaid. hollow handle separated from each other and forming a liquidchamber between them, a reciprocating part passing through openings'insaid guides so as to fit tightly therein and prevent the escape of oilbetween the engaging faces of thereciprocating part and the guides, apassageway through said reciprocating part and cornthe space between theguides and having its exit end opposite one of said guides so as to beclosed thereby when the reciprocating part is in its normal position,means for moving` said reciprocatingpart so that the exit end ott said'passageway moves beyond the guide to permit the escape ofthe liquid fromthe liquid chamber.
